Child sexual abuse is a pervasive crime that has numerous negative short and long-term impacts on its victims, as well as negative impacts for society. Modus Operandi (MO) is defined as a pattern of perpetration utilized by those who commit CSA to successfully abuse a child without detection. Understanding how CSA is perpetrated through MO is essential, as this construct influences both prevention of CSA, and treatment for victims and perpetrators. The Modus Operandi Questionnaire (Kaufman, 1991; MOQ) is the first and most comprehensive measurement tool for CSA MO, and is utilized by both researchers and clinicians. This study provides an up-to-date factor analysis of the MOQ, breaking the measure into five stage-based scales (i.e.; Accessing the victim, Gaining the victim's trust, Gaining the victim's cooperation, Sexual Abuse, and Silencing after the abuse). Each stage-based scale was analyzed through Exploratory Factor Analysis to determine structure followed by a Confirmatory Factor Analysis to examine model fit, as well as loadings of first-order factors onto their respective stage-based second order factors. Although model fit for all five scales can be improved, the results of this study determined reliable factors within all five scales, and show a structure that can be utilized to further inform research, treatment, and prevention of CSA.
